ABSTRACT:
A tool extender to bridge the space between a person and a portable tool to be remotely actuated by the person includes cradle means engageable with the tool and at least one guide rod attached to the cradle means and slidable within a bridge support. A strap is attached to the bridge support and is adjustable to engage a handle of the tool, whereby the strap and cradle means jointly support the tool. A mount, such as a shoulder mount, arm mount, elbow mount, or the like is attached to an elongated arm structure which extends to the bridge support. A trigger actuation mechanism includes a cord which extends from a grip element, along the elongated arm structure, to a hook engageable with a tool trigger. The trigger actuation mechanism is operable by manual squeezing of the grip element toward the mount and away from the hook. The guide rods, cord, and strap are adjustable for accommodating various sized tools. A handle is removably attached to the elongated arm structure. The elongated arm structure of the tool extender may include a first arm structure, a second arm structure, and a pivotal connection attached therebetween, enabling one of the arm structures to be inclined at an angle with respect to the other of the arm structures. The pivotal connection and adjustable handle provide for various positioning of the tool extender with respect to a workpiece and operator of the tool.
